[alsa-devel] [PATCH 0/5] ASoC: Intel: IPC framework updates

[Cezary Rojewski]

Existing IPC framework omits crucial part of the entire communication:
reply header. Some IPCs cannot function at all without the access to
said header. Update the sst-ipc with new sst_ipc_message structure to
represent both request and reply allowing reply-processing handlers to
save received responses.

Despite the range of changes required for model to be updated, no
functional changes are made for core hanswell, baytrail and skylake
message handlers. Reply-processing handlers now save received response
header yet no usage is added by default.

To allow for future changes, righful kings of IPC kingdom need to be put
back on the throne. This update addresses one of them: LARGE_CONFIG_GET.

Cezary Rojewski (5):
  ASoC: Intel: Update request-reply IPC model
  ASoC: Intel: Haswell: Align with updated request-reply model
  ASoC: Intel: Baytrail: Align with updated request-reply model
  ASoC: Intel: Skylake: Align with updated request-reply model
  ASoC: Intel: Skylake: large_config_get overhaul
